+  Alternative Options (Replace the "relnote: none" line above with one of these if applicable):
+
+  1. For a user-facing change:
+     relnote: Added support for second-generation memory allocation optimizations
+
+  2. For a manual/legacy override (stops the script from automatically appending this PR number):
+     relnote: Consolidated memory allocation upgrades (#884, #885)
+
+  Multiple relnotes may be included in a single PR, each with their own relnote line
